Read MoreRegenerative Braking, or "Regen" for short, allows electric cars to recapture energy that is wasted when braking. In a gas car, the act of braking is an attempt to absorb the energy of the car moving forward – in effect, stopping it. However, the energy absorbed by the brake pads isn''t re-used by the vehicle; instead, the energy is
